I hope it takes a very very long time for them to impliment PvP. As that will be the point in which the game will see class after class get hosed, in the name of balancing. Never fails, happens in every MMO when they add PvP some time after launch. Abilities always work differently against player characters then they do in ame mob npcs. PvPers will cry foul WHEN one class has an ability or two that is OP in PvP. They will foolishly nerf it for the sake of the PvPers who cry all over the forums. Now the OP PvP spells that were decent to good PvE spells, will be nerfed and useless PvE.

I have never seen an MMO that had PvP introduced sometime after launch that did not ruin PvE.
